Hi all On my iPhone 5 I quite frequently make calls where the recipient can hear me, but I can't hear them. I place the call, and to me it's just silent, but I eventually realise the call actually went through because there's a call timer showing on the screen. I then have to hang up and redial the person to be able to hear them. Additionally, I'll sometimes place a call and I won't hear any ring tone, but the person at the other end picks up and I can hear them. Does anyone know what's wrong with my phone? I've had three iPhone 5s and it's happened on all of them. Many thanks #29.
